The invention relates to mechanical move-.

ments for converting reciprocatory into rotary motion or vice versa, andwhile it is herein disclosed for transmitting motion from pistons to ashaft, it is to be understood that i it is not restricted to anyparticular field of use. 1

One object of the invention is to provide a new and improvedconstruction and relation of elements for smoothly convertingreciprocatory into rotary motion or vice versa, embodying reciprocatorymembers transverse to the shaft.

Another object of the invention is to prowell adapted for use in themanufacture of engines having cylinders ranging in number from one toeight.

In the form of construction shown in Figs.

1 to 41, the numeral 15 denotesa shaft mount ed in appropriate bearings16 and having a fiy-wheel 17. An annular wobbler 18 circumscribes theshaft 15 and the latter is provided wlth means for wobbling saidWobbler. A ball 19 or a central section of a ball is either secured toor integral with the shaft 15 and is provided with continuous ball races20 in planes oblique to said shaft. Bearing balls 21 are engaged withthese'races and with other races 22 in the Wobbler 18. While two sets ofballs and races are shown, any desired number of sets could of course beused. In fact, the gist of the present invention is not concerned withany particular means for connecting the Wobbler operatively with theshaft.

For illustrative purposes, two fixed supports 23 are shown spacedoutwardly in opposite directions from the shaft 15 and the wobbler 18.In an engine, compressor or the like, the equivalents of these supports23 may be formed by opposite walls ofa crank case or the like. 7 A novellever member 24 is mounted on the supports 23, is connected with fourpiston rods or connecting rods 25. Two of these rods are at one side ofthe shaft 15 and two at the other side thereof, and two of said rods arespaced in one direction from the fulcrum axis of the lever 24:, whilethe other two are spaced in the opposite direction from said axis. Whenconstructing a four cylinder engine or the like, all of the rods 25 Willextend in the same direction, as shown. and will be connected with thepistons 26 of the four cylinders 27 In constructing an eight cylindermachine, in addition to extending four of the rods 25 in the directionherein shown, four more would be extended in the opposite direction andconnected with the pistons of additional cylinders.

The lever 24 embodies two opposed, elongated side portions28 and anarched connecting portion 29 whose ends are integral with the centralportions of said side portions 1 Feb. 2, 1932. E. BRAINARD 1,843,331

HARROW HITCH Original Filed Nov. 16, 1929 2 Sheets-Sheet 2 By flaw (206mA itorney Fatentecl Feb. 2, 1932 UITED ST ELMER BRAILN'ARD, on again,OKLAHOMA- teaser EAR-ROW rr-Ircrr Application filed November 16, 1929,Serial No. 407,719. Renewed August :18, 1931.

The present invention relates to a harrow hitch and has for its primeobject to provide a hitch structure wherein the draft is distributed soas to eliminate the liability of the breaking of the beam particularlywhen the harrow is being turned at a corner or being turned completelyaround,

Another very important object of the invention resides in the provisionof a harrow hitch structure of this nature which is simple in itsconstruction, strong and durable, and thoroughly eficient and reliablein use and features of construction, and in the combination andarrangement of parts as will be hereinafter more fully described andclaimed.

In the drawings: Figure 1 is a top plan view of the structure embodyingthe feature of my invention,

Figure 2 is a rear elevation of the beam, 7 Figure 3 is a sectional viewtaken substantially on the line 33 of Figure 2,

Figure 4 is a sectional view taken substantially on the line 44 ofFigure 1, and

Figure 5 is a sectional view taken substantially on the line 55 ofFigure 1.

Referring to the drawings in detail it will be seen that the numeral 5denotes an elongated transverse beam on the top of the central half ofwhich is fixed, a bar 6. A pair of straps 7 are secured to the centersof the bar. 6 and the beam 5 and project forwardly.

Their forward ends are spaced closer together than their rear ends andbetween said forward ends is journaled a sleeve or pulle 8.

A pair of link rods 9 are secured to eye bolts 10 through intermediatepoints of the outer quarters of the beam 5 and diverge in wardlyforwardly with respect to each other terminating in eyes 11. In otherwords, the rods are engaged with the intermediate portions of the beamadjacent the ends thereof and terminate in eyes, as shown in Figure 1. Adraw bar 12 has a segment 14 secured thereto which in turn is engagedwith the ring 15. A chain 16 is trained over the sleeve 8,

throughsthe eyes 11 .andhas its ends secured to the ring 15. p Y

I IzIa-rrowsare denoted 'by'the letter Hand have link connections'L withthe beam 5, so as to drag behind the beam ,as it isxpulled along; Thislink structure L is illustrated to advantage inzFigure 5 comprising :an'eye 20 swiveled an 'the, frame f the-:harrow secured to an oblong link21 which in turn is I secured to the eye of an eye,boltt22ex-tendingzthrough and fixed in thebeam 5.

{The purpose .of this draft structure ,is to provide thestrainstresseson :the beam so as to keep the same from breaking in the centerparticularly when turning corners.

- The pulley or sleeve allows the chain to shift so that the pullistaken ,care of from the proper side depending upon the 5 direction inwhich the turn is being made.

- It is thought that the construction,-op.era-' tion, utilityandadvantages of this lnvention will now be quite apparent to those skilledin this art without a more detailed description hereof.

The present embodiment of the invention a has been described inconsiderable detail merely for the purposes of exemplification since inactual practice it attains the features of advantage enumerated asdesirable in the statement of the invention and the above description.

It will be apparent that changes in the dc I tails of construction, andin the combination and arrangement of parts may'be'resorted to withoutdeparting from the spirit or scope of the invention as hereinafterclaimed or sacri- I ficing any of its advantages.

"Having thus described my invention, what I claim as new is:

of the cross beam, rods engaged with the, in-

termediate portions of the beam adjacent the ends thereof andterminating in eyes, a chain trained over the pulley and through theeyes and having its ends attached to a ring forwardly disposed, a barfixed to the central half of the beam.

3. In a harrow,a cross beam,a pulley,means for mounting the pulley atthe center of the cross beam, rods engaged with the intermediateportions of the beam adjacent the ends thereof and terminating in eyes,a chain trained over the pulley and through the eyes and having its endsattached to a ring forwardly disposed, a bar fixed to the central halfof the beam, said means for supporting the pulley comprising strapsfixedto the central portions of the bar and the beam and pro jectingforwardly with the pulley journaled between the forward ends thereof.

4. In a harrow, a cross beam, a pulley, means for mounting the pulley atthe center of the cross beam, rods engaged withthe intermediate portionsof the beam adjacentthe ends thereof and terminatingin eyes, achaintrained over the pulley and through the eyes, and having its endsattached to a ring forwardly disposed, a bar fixed to the central halfof the beam, said means for supporting the pulley comprising strapsfixed to the central portions of the bar and the beam and projectingforwardly with the pulley ournaled between the forward ends thereof, aplurality of harrows and link connections between the barrows and thebeam.

In testimony whereof I afiix my signature.
